We’re told cops have already decided to refer the case to prosecutors, even though the investigation is far from complete. They have requested to interview the Biebs, but he’s in Norway now. It’s pretty typical for police to refer high-profile cases to prosecutors.

Over the weekend, Bieber allegedly committed criminal battery against a photographer in Calabasas Sunday afternoon. The pap called 911 after the scuffle, but by the time cops arrived, the singer had split.

He was taken to a nearby hospital in an ambulance then to the police station where he filed a police report naming Bieber as the culprit.

If the Biebs is charged and convicted, he would face 6 months in jail.
